Abstract
The utility model relates to a water jetting box of a steam turbine. The water jetting box of the steam turbine is characterized by comprising a box body (1), wherein a water inlet hole (2) is formed in the top of one side of the box body (1), a water outlet hole (3) is formed in the side wall of the other side of the box body (1), and a water blocking board (4) is vertically arranged inside the box body (1). A gap is arranged between the water blocking board (4) and the top of the box body (1). A steam blocking board (5) is vertically arranged on the water blocking board (4) and is a steam blocking board in honeycomb shape. A plurality of small holes are formed in the steam blocking board (5). An air venting hole (6) is formed in the top of the box body (1). The water jetting box of the steam turbine is in a steel board structure, heat dissipation performance is good, the honeycomb type steam blocking board (5) is added in the water jetting box, water which enters a water jetting pump is prevented from being steam-water mixture, vacuum of a condenser of the steam turbine can be ensured, power generation air-consumption can be small, and efficiency is high.
Description
Technical field
The utility model relates to a kind of jetting case of steam turbine.
Background technique
Steam turbine is the rotary power machinery that the transformation of energy of steam is become mechanical work, claims again steam turbine.Main prime mover as generating usefulness also can directly drive various pumps, blower fan, compressor and propeller for vessels etc., can also utilize the steam discharge of steam turbine or intermediate extraction to satisfy production and heat supply needs in life.Water jet system in the steam turbine is mainly one with the whole jetting case that waters structure of reinforced concrete, yet jetting case in the past exists following defective: the poor radiation of jetting case, carbonated drink isolation mounting effect is bad in the jetting case, directly affected the vacuum of turbine condenser, cause the generating gas consumption to increase Efficiency Decreasing.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of thermal diffusivity good, and the carbonated drink isolation effect is good, and the generating gas consumption is little, the jetting case of the steam turbine that efficient is high.
The purpose of this utility model is achieved in that
The jetting case of the utility model steam turbine, comprise casing, the top of one side of described casing has the water inlet, have osculum on the sidewall of opposite side, the inside of described casing vertically is provided with a manger board, and the gap is left at described manger board and casing top, the steam retaining plate of vertical setting is set on the described manger board, described steam retaining plate is cellular steam retaining plate, offers some apertures on the plate, and the top of described casing also has exhaust port.
The jetting case of the utility model steam turbine has the following advantages:
The jetting case of the utility model steam turbine is steel plate structure, and thermal diffusivity is good, has increased the honeycomb steam retaining plate in the jetting case, and the water of having guaranteed to enter in the water-jet pump is not steam water interface, has guaranteed the vacuum of turbine condenser, so that the generating gas consumption is little, efficient is high.
Description of drawings
Fig. 1 is the structural representation of the jetting case of the utility model steam turbine.
Among the figure: casing 1, water inlet 2, osculum 3, manger board 4, steam retaining plate 5, exhaust port 6.
Embodiment
Referring to Fig. 1, the utility model relates to a kind of jetting case of steam turbine, comprise casing 1, casing 1 is made for steel plate, the top of one side of described casing 1 has water inlet 2, have osculum 3 on the sidewall of opposite side, the inside of described casing 1 vertically is provided with a manger board 4, described manger board 4 leaves the gap with casing 1 top, and about casing 1 is divided into two, the steam retaining plate 5 of vertical setting is set on the described manger board 4, described steam retaining plate 5 is cellular steam retaining plate, offer some apertures on the plate and be used for ventilation, the top of described casing 1 also has exhaust port 6 and is used for exhaust.
The jetting case of the utility model steam turbine is steel plate structure, and thermal diffusivity is good, has increased the honeycomb steam retaining plate in the jetting case, and the water of having guaranteed to enter in the water-jet pump is not steam water interface, has guaranteed the vacuum of turbine condenser, so that the generating gas consumption is little, efficient is high.
